Supply voltage glitches are a well-known fault injection method used to attack electronic circuits. The aim of this paper is to identify the specific threats of mixed signal systems and to provide some solutions to ensure their security. Indeed, many Systems on Chip use both analog and digital circuits but, most of the time, the security of such application(More)
The use of a laser as a means to inject errors during the computations of a secure integrated circuit (IC) for the purpose of retrieving secret data was first reported in 2002. Since then, a lot of research work, mainly experimental, has been carried out to study this threat. This paper reports research conducted, in the framework of the french national(More)
This paper presents a study on the effect of Forward Body Biasing on the laser fault sensitivity of a CMOS 90nm microcontroller. Tests were performed on a register of this target, under several supply voltage and body bias settings, showing significant laser sensitivity variations. Based on these results, a method which aims at decreasing fault(More)
As security constraints are becoming more and more important, even for low-cost and low-power devices, new attacks and countermeasures are constantly proposed. Following this trend, Body Bias Injection (BBI) was introduced a few years ago. This new fault injection method consists in applying a high voltage pulse on the circuit substrate to induce faults.(More)
